DUMP-CAR.

Specification of Letters Patent.

Patented Jan. 1-, .1921.

Application filed January 21, 1919. Serial No. 272,266.

To all whom it may con cern:

Be 1t known that we, WILLIAM L. BURNER and JAMES H. COTTON, citizens ofthe United States, residing at Columbus, in the county of Franklin andState of Ohio, have invented certain new and useful Improvements inDump-Cars, of which the following is a specification.

The invention relates to a door lock for the swinging door provided on adump car, and is especially adapted for use in a car having a bodypivoted near the lower edge of one end thereof and adapted to swingabout the pivot to effect a discharge of the contents thereof. The lockis adapted for manipulation positively both upon opening and closing ofthe car door, and is arranged to permit a partial opening of the doorand to maintain that position until the operator desires to effect amore complete opening, the entire matter being in the discretion of theoperator. Essentially the invention comprises a lock member, asupporting member therefor, a manipulating rod and a lever associatedwith the opposite end of said rod for the purpose of giving the roddirection in its lock manipulating funo tions.

In the drawings which are hereto attached and hereby made a part of thisspecification the figure shows a dump car in side elevation with theinvention attached thereto, the dumped position of the body beingindicated in dotted lines.

Referring to the drawing 1 is the underframe of a car having the body 2mounted thereon and pivoted at 3 to be tilted and dumped as indicated.4: is the door pivoted at 5 to swing outwardly away from the end of thecar body when the dumping operation is taking place, and carryingthereon the striker bar 6: the hook member 7 is pivotally' supported at8 by the bar 9 pivotally de pending at 10 on the end of the car body andimparting to the hook member as the latter is moved an arcwise motion.At 11 is pivoted the rod 12 which at its opposite end is pivoted to thebell crank lever 13 at 1 1. Said lever is adapted to be grasped by theoperator and swung on its pivot 15 to engage or release the locking hookmember 7.

Assuming the door 4 to be in its closed position and looked as shown inthe figure, to open the door the operator grasps the lever 13 and drawsit downwardly thereby swinging the end of the rod at 14: in an arc,which will result in imparting a longitudinal movement to the rod afterthe pivotal point 14 has passed below the horizontal plane of thepivotal point 15, thereby thrusting the hook member 7 rearwardly on itssupporting bar 9, and the latter will also impart an arcwise movement tothe hook member as the manipulation of the rod 12 continues. The rotarymovement induced in the hook member by the thrust of the rod 12 tendsconstantly to bring the hook member to an unlocking position, but thiscom plete unlocking is counteracted for a little time by the swinging ofthe supporting member or bar 9 which tends to bring the hook member to alower position. The result of the construction and manipulation is tothrust the hook away from contact with the door permitting the door toswing open a little to permit a discharge of the lading in smallquantity as desired and upon a further manipulation of the lever 13 thehook member may be entirely released from the door and the lading thenis free to pour forth in mass. The door may be maintained in thisposition just short of being unlocked so long as the operator wishes,the advantage being that the lading may be spread or strewn instead ofbeing dumped, or both practices may be resorted to at will.

It will be noted that the rod 12 is suspended from its ends at itspivotal connections and that its entire movement is such only as isimparted to it positively by the lever 13.

When the door is swung back to closed position as the car body isrighted. the hook member is drawn into engagement there with by therotation of the lever 13 back to its position illustrated in the heavylines in the drawing. The quadrant 16 secured to the front end of thebody may be provided with notches or other stop means for the leverwhich will enable the operator to lock the lever 13 in any positiondesired.

What we claim as new is In a vehicle having a body adapted for thereception of lading and the discharge of said lading through one endthereof, a door for said body pivotally suspended from its upper edge topermit the discharge of lading and to effect the closure of thedischarge opening, a bar member pivotally mounted on said body adjacentsaid door, a hook member pivotally mounted on said bar memher forarcwise movement, an operatingrod extending along said body pivotallyconnectedwith said hook member, and manipulating means associated Withthe opposite end of said rod adapted to urge said hook member rearwardlyto permit the opening of said door and to retract said hook member 10 toeffect the closing of said door.

In testimony whereof We affix our signatures in the presence of twoWitnesses.
